Steve McClaren wants to give Derby supporters a team to be proud of on his return to the Sky Bet Championship club.
The former Rams boss is back at the iPro Stadium 17 months after leaving, putting pen to paper on a deal until 2018.
He succeeds Nigel Pearson after he left last week following a suspension and club investigation into his conduct last month.
McClaren pledged the same thing in 2013 at the beginning of his first spell as manager, when his time in charge became synonymous with high-tempo attacking football which got supporters on their feet.
McClaren, now in his fourth spell at Derby having also played for the club and been assistant to Jim Smith in the 1990s, wants to get the iPro Stadium buzzing again but has warned it may not happen straight away.
"I've been watching the team and the progress being made since I've been away," said the former England boss at his press conference on Friday afternoon.
"Derby has signed some damn good players and the potential is there. Now we have to work together and produce a team the supporters once again can be proud of.
"The way we played three years ago wasn't just successful in 2013-14, but also in the season afterwards as well. We'll look at the players and the capabilities they have. Will we play the same way again? Why not?
"We were always an exciting, attacking football team. That's what I want to see.
"But it's not going to happen over night, it's going to take some hard work. Chemistry and gelling takes time."
